heartbeat mechanism to audit the SIP server health status.
Once enabled, OPTIONS traffic should be sent whenever
the account is registered. OPTIONS traffic will occur
periodically according to the keep-alive interval.
Keep Alive interval
(secs)
Set the interval at which the OPTIONS for the keep-alive
mechanism are sent.
Ignore Keep Alive
Failure
Enable the phone to ignore keep-alive failure, if the failure
can trigger account re-registration and re-subscription (and
active calls are dropped).
